MIT engineers design a system for IoT chips to do quantum-computer-proof encryption
One of the most frequently mentioned fears about future quantum computers is that they will someday crack our encryption codes and lay all our digital secrets bare. Despite it being a truly far-off possibility, cryptographers are already taking the threat very seriously.
The solution seems to be to develop one or more classes of encryption schemes that classical computers can use but quantum computers can’t crack. Less than two weeks ago, the U.S. National Institute of Standards and Technology reported that its search for quantum-proof algorithms had reached the semifinals stage. Following a year-long evaluation, the agency has narrowed the field down to 26 algorithms, most of which fall into three broad families.
Now, at the IEEE International Solid-State Circuits Conference on Monday in San Francisco, engineers from MIT have reported the creation of an encryption system that performs one of these schemes on a chip small enough and energy-efficient enough to guard battery-powered nodes on the Internet of Things from future quantum attack.
